GRU M1 Listing Validation
Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation
Purpose
This document defines acceptance gates and validation criteria for GRU M1 compliant settlement instruments (cUSDC, cUSDT, cEURC, etc.) prior to and after listing on CoinMarketCap (CMC) and CoinGecko (CG).
Hard Gates (Acceptance Criteria)
| Metric | Threshold | Rationale |
|---|---|---|
| Peg Deviation | ≤ ±0.50% | Target price = 1.0000; variance band for operational tolerance |
| Recovery Time | ≤ 24 hours | Time to return to peg band after stress event |
| Supply Reconciliation Error | 0 | On-chain supply must match attested supply exactly |
| Unexplained Variance | None | No unexplained supply changes; full audit trail |
Failure of any gate: Corrective action required before listing or scaling. No exceptions.
Pre-Listing Validation
Dry-Run Requirements
- Dominance Simulation — Complete S0–S5 scenarios; archive results
- Peg Stress-Test — All P1–P6 tests pass per instrument
- Supply Check — On-chain supply reconciled with attestation
Documentation Requirements
- Symbol registry table (frozen)
- External classification matrix
- Mint/burn policy
- Reserve attestation summary
- Peg maintenance memo
See: GRU M1 Master Implementation Plan
Post-Listing Validation
T+1 / T+7 / T+30 Checks
| Checkpoint | Price | Supply | Category | Market Cap |
|---|---|---|---|---|
| T+1 | Correct | Correct | Stablecoin/Fiat-Pegged | Correct |
| T+7 | Correct | Correct | Correct | Correct |
| T+30 | Correct | Correct | Correct | Correct |
Incident Triggers
| Trigger | Action |
|---|---|
| Peg deviation > ±0.50% | Immediate disclosure; indexer communication |
| Supply mismatch | Corrective data submission; pause if critical |
| Misclassification | Corrective data submission to CMC/CG |
See: GRU M1 Listing Dry-Run Runbook
Compliance Cross-Reference
This validation framework supports:
- Regulatory Compliance — Auditable evidence for institutional, banking, and sovereign review
- Operational Compliance — Runbooks, incident response, recovery procedures
- Financial Compliance — Transaction logging, balance tracking, attestation
